BACKGROUND OF THE PRESENT INVENTION Field of Invention

The field of this invention relates to an Edible Pet Chew.

Description of Related Arts

Domestic pets, primarily dogs, have an instinct to chew which keepstheir teeth healthy, exercises their jaws and teeth and keeps teethclean. “Pet Chew” products have been introduced to the market for manyyears to accommodate that instinctive urge to chew in a healthydirection.

“Pet Chews” are intended to be chewed by a pet/dog for an extendedperiod of time before being digested. A great part of pet chew productsin the market are traditional Bully Sticks welcome very much by dogs andconsumers, which are made of natural bovine penis. Generally foreskin ofbovine penis is removed, cleaned and then dehydrated by for exampleheating or freeze-drying. It enjoys an inherent “good palatability” and“durability (after dehydrating process)” which makes it an outstandingsuccessful product in the trade.

However, traditional bully stick products have some drawbacks, suchas: 1. extremely high price per gram. Due to the natural scarcityproperty with the source of natural bovine pizzle, raw materials (bovinepizzle) for producing traditional bully sticks are sold at an extremelyhigh price, which creates the final products, traditional bully sticks,being sold to consumers at an extremely high price. 2. Materially hardto acquisition due to natural scarcity property with the source ofnatural bovine pizzle.

In the market, there's another popular products in a form of extrudedstick, typically formulated by plant based materials, enjoying a lowcost materials. Also, it is a product with “durability” property whichcan provide a long chewing time for dogs. However these kind of productsare sold by many distributors/retailers under a great competition. Thecompetition is a homogeneous one, in which a product is hard to be welldistinguished from another. A homogeneity product is hard to attractconsumers to buy.

What is required is to provide a pet chew overcoming the drawbacksabove-mentioned accompanying the existing traditional bully stickproduct and extruded stick products.

U.S. patent application Ser. No. 13/858,592 by Shrestha, filed on Apr.8, 2013, disclosed a pet chew comprising a hardened cheese and a dryanimal tissue such as bully sticks attached to the cheese piece. And italso disclosed a kind of animal tissue puff such as bully puff. However,the bully sticks or bully puff it attempted to apply as still istraditional bully sticks, no new matters. It still has the drawbacks oftraditionally bully stick as aforementioned.

U.S. Pat. No. 8,479,687 by Anderson, filed on Feb. 14, 2007, disclosed apet chew with rawhide and traditional bully stick (or steer penis) woventogether. Since it's still a traditional bully stick product, it suffersthe drawbacks of traditional bully stick aforementioned.

U.S. Pat. No. 8,074,609 B2 by Grant Adkins, filed on Mar. 25, 2010,disclosed a rawhide pet chew with a traditional bully stick wrapped in.But since it's still a traditional bully stick product, it suffers thedrawbacks of traditional bully stick aforementioned.

U.S. Pat. No. 7,677,203 by Stern, filed on Nov. 21, 2006, disclosed apet chew with a plant based outer casing and a chewy edible materialpositioned within the casing. However, it is silent about an intentionto make a bully-stick-like product imitating bully stick. The productsit disclosed have nothing to do with traditional bully stick, whichdoesn't have any features of imitating traditional bully stick. And itfails to disclose an extruded pet chew with pizzle ingredient.

U.S. patent application Ser. No. 14/295,009 by Doerr, filed on Jun. 3,2014, disclosed a pet chew comprising an amylase filling and a collagencasing. However it is silent about an intention to form a pet chew thatis artificial bully stick (or Bully-Stick-LIKE). It lacks of allnecessary features that a traditional bully stick presents, for examplebully stick shapes and structure. Thus it fails to attract consumers byworking as a new product alternative to traditional bull stick product.Furthermore, it has a filling center that may use 40% bully pizzlematerial, however it fails to disclose how many pizzle ingredientpercentage in weight exists in whole product formula, which makes itunable to label the product as “with pizzle” according to AAFCO rule. Adisadvantage with this product is that, it has a collagen outer casing,where collagen material is considered to incur disadvantages such as: A,collagen material isn't inherently attractive making it fail to urgedogs to chew; B, manufacture of animal hide and collagen is relativelyunregulated industry. It may create pollution to environment. H2O2 andNaOH chemicals that are used for rawhide manufacture and heavy metalsmay remain in finished products which harms dogs' health.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The following description is disclosed to enable any person skilled inthe art to make and use the present invention. Preferred embodiments areprovided in the following description only as examples and modificationswill be apparent to those skilled in the art. The general principlesdefined in the following description would be applied to otherembodiments, alternatives, modifications, equivalents, and applicationswithout departing from the spirit and scope of the present invention.

It should be noted that the term of “Bully stick” refers to a pet chewproduct of dehydrated animal (especially but not limited to bovineanimal, bovine especially refers to bull or steer) pizzle, or segmentthereof, for dogs to chew on, where the pizzle is derived from a naturalanimal penis cut from slaughtered animals (especially bovine), typicallywith foreskin being removed. Bovine (especially bull or steer) penis,known in pet chew market as pizzles. This bully stick is so calledtraditional bully stick made of dehydrated a natural part of an animal(especially bovine).

Pet chew stick of present invention is intended to work as analternative to traditional GENUINE Bully Sticks aforementioned.

The term of “Artificial Bully Stick pet chew” (or say Bully-Stick-LIKEpet chew) in present invention refers a pet chew or a pet chew member ina shape of stick formed from a composition material, imitating thefeatures of traditional GENUINE bully stick product including structure,and/or appearance, and/or size, and/or color, and/or texture, and/orflavor, and/or durability, and/or palatability, but it is not atraditional GENUINE bully stick.

It is known that a market-popular pet chew product should include twomajor factors, i.e. property of “chewy” (durability) and property of“inherently good palatability”. “Chewy” means a material that can endurea dog's chewing for a long time before its being ingested. “Goodpalatability” means a material with inherent attractant to dogs withoutadding additional artificial flavorings. A market-successful pet chewproduct is required to have both properties. Artificial Bully Stick petchew disclosed by present invention is a product with both “inherentlygood palatability” and “durability”.

Before disclosing present invention, as a prior art, let's address atypical specification/structure and manufacturing process for thesetraditional GENUINE Bully Stick products as follows (from points 1 to6):

1. Prepare natural flesh of pizzle. Now refer to FIG. 6 (Prior Art),0600 gets ready which is cut from slaughtered bovine animal. 0601 isroot of the bovine penis. Shaft part from point 0601 to 0602 is atypical portion of pizzle that is applied to make Bully Sticks. 0603 isglans of a pizzle, which is also can be included in finished products insome specific products.

2. FIG. 7 (Prior Art) is a segment of fresh pizzle. 0703 refers to agroove longitudinally along the whole pizzle. 0701 is muscle of thepizzle, serving as an outer layer for the whole pizzle piecedistinguished from the inner member 0702. 0704 is the surface of thepizzle. 0702 includes tissues of corpus cavernosum, spongiosum, urethra,etc.

3. Having pizzle dehydrated by for example solar drying, heating orfreeze drying. FIG. 8 (Prior Art) is a cross section figure for a finalbully stick product after dehydrating process. This cross section iswith a typical outline shape similar to letter “B”. 0801 is dehydratedmuscle with hard quality. 0802 is dehydrated corpus cavernosum. 0803refers to a groove longitudinally along the pizzle. 0804 is dehydratedspongiosum.

4. FIG. 9 (Prior Art) is a final product, a dehydrated bully stick witha typical cross section outline shape similar to letter “B”. 0901 and0904 is hard outer layer of the bully stick made of dehydrated muscle.0902 is inner member including tissues of corpus cavernosum, spongiosum,urethra, etc. 0903 refers to a groove longitudinally along the wholebully sticks body.

5. 1101, 1102, 1103 and 1104 in FIG. 11 (Prior Art) reflect a group ofvarious cross section outline shapes that traditional bully sticks mayhave. Also 1201 to 1207 in FIG. 12 (Prior Art) reflect a group ofvarious cross section outline shapes that traditional bully sticks mayhave

6. Typical outstanding features (including structure features) of BullyStick product are derived from and determined by aforementioned naturalbovine penis natural features. It is disclosed by present inventor that,traditional bully stick product has its essential typical features asfollows (from A to K):

A. Bully stick includes an outer layer and an inner member, where theformer holds the latter by surrounding it. This structure is derivedfrom pizzle inherent structure. The outer layer is formed by muscle andinner member formed by tissues of corpus cavernosum, spongiosum,urethra, etc. Products in FIG. 8 (Prior Art) and 9 (Prior Art) reflectthis pet chew structure.

B. After being dehydrated, inherently, the outer layer of Bully Stickformed by muscle enjoys a property of getting hard. The hardness ideallyaccommodates dog's chewing desire, making it an ideal pet chew product.Traditional bully stick makes itself outstanding with a longestdurability hardness.

C. It is inherently a stick shape product. And in some other bully stickproducts, it is initially a stick shape and is finally manipulated to adesired shape for example Spiral or Braid different from initial stickshape.

D. Bully stick has pizzle ingredient, which is a very strong flavorproduct enjoying an irresistible attraction to dogs. Pizzle ingredientoffers “inherently good palatability” for the pet chew.

E. Cross section of traditional bully stick presents characteristicoutline shapes. A typical outline is in a shape similar to letter “B”,or peanut, or arabic numerals “8”. Products in FIG. 8 (Prior Art) and 9(Prior Art) reflect this feature. Some other outline shapes aredescribed in FIG. 11 (Prior Art) and 12 (Prior Art). (These outlineshapes created by inherent feature of natural pizzles)

F. An inherent groove appears longitudinally along the whole BullySticks body. Products in FIGS. 8 and 9 reflect this feature.

G. Typical properties of the outer layer include: beingsemi-transparent, and with fiber-like texture. (these two properties ofouter layer are created by the nature of the muscle that forms the outerlayer)

H. Typical range of thickness of the outer layer is 1 mm-5 mm.

I. Typical properties of the inner member include: spongy, comparativelymore unconsolidated or looser in texture than the muscle outer layer.For example FIGS. 8 and 9, product 0800/0900 has an inner member0802/0902 which includes tissues of corpus cavernosum, spongiosum,urethra, which is unconsolidated. And there are some small holes spreadsubstantially homogeneously to the inner member body. Refer to FIG. 8,0802 from bully stick has tiny holes. (these properties of inner memberare created by the nature of corpus cavernosum and/or spongiosum tissuesthat exist in a pizzle)

J. Inner member color is lighter than outer layer color. Inner membercolor is typically white or yellowing white. Outer layer color istypically light brown, brown, dark brown, red brown or muscle color. Forexample 0902 from pet chew 0900 is in white color and 0901 is in lightbrown. Density of inner member is lighter than Bully Stick outer layer.For example 0902 is lighter than 0901 in density. (these properties ofcolor recognition are created by the nature of a pizzle)

K. Pizzle flavor. Traditional bully stick has an inherent characteristicpizzle flavor, which greatly attracts dogs to chew.

All prior arts are silent with an intention to well imitate traditionalBully Stick with a composition material replacing the natural animalpizzle products. This new product requires surprising invention, where askilled person with ordinary skills in this art can't disclose it.Especially, all prior arts are silent to create a pet chew with featuresof the following as a whole: it's an extruded stick with pizzleingredient and plant ingredient, with a hard outer layers and an innermember, with cross section outline shape of “B”, or peanut, or “8” andwith a groove longitudinally along its stick body.

It is also surprisingly disclosed by present inventor that, primaryfeatures of present invention are to imitate theproperties/features/structure of traditional Bully Stick aforementioned.It's disclosed by present inventor that, a pet chew product mustnecessarily bear at least one property/feature as described above(especially A, B and C), OR, the pet chew will fail to imitatetraditional Bully Sticks.

Artificial Bully Stick (or Bully-Stick-LIKE) Pet Chew of presentinvention imitating genuine bully stick is now being disclosed to serveas an alternative to traditional GENUINE Bully Sticks aforementioned,with significantly lower product cost, imitating some necessaryproperties or features (at least including appearance features) oftraditional Bully Stick. Artificial Bully Stick Pet Chew disclosed bypresent invention is distinguished from traditional Bully Sticks, whichis typically an extruded stick product formed with a compositionmaterial with ground bovine pizzle. As a contrast, traditional BullyStick is substantially a single ingredient product without beingprocessed other than dehydrating process.

One advantage of the Artificial Bully Stick pet chew of presentinvention is hugely cheaper material cost than traditional bully stick.The Artificial Bully Stick pet chew is extremely cheaper thantraditional bully stick which is made of substantially 100% bovinepizzle. The latter could be 4 times of the price of the former. Due tothe natural scarcity property with the source of natural bovine pizzle,raw materials (bovine pizzle) for producing traditional bully sticks aresold at an extremely high price, which creates the final products,traditional bully sticks, being sold to consumers at an extremely highprice. Another advantage is, easier acquisition of raw material v.s.traditional bully stick products. Producing traditional bully stickproducts requires huge volume of natural animal pizzle. The ArtificialBully Stick pet chew of present invention is formed from a compositionpartially with pizzle ingredient. For example the composition has 10%pizzle in formula (90% is non-pizzle ingredient which is extremelyacquisition-easier material than pizzle), in which producing thisproduct just requires one tenth of pizzle material to manufacture thesame quantity of finished products v.s. traditional bully stickproducts. Preparing the composition materials for production ofArtificial Bully Stick pet chew is much more easier than traditionalbully sticks.

Preferably, the Artificial Bully Stick (or Bully-Stick-LIKE) pet chew(or pet chew member) of present invention includes an outer layer and aninner member, where the former holds the latter by surrounding it, in apurpose to imitate a typical feature of traditional Bully Sticks.Preferably, the thickness of the outer layer is homogenous along thewhole stick body, like traditional bully stick. Now refer to FIG. 1,0100 is an extruded pet chew with outer layer of 0101 and inner memberof 0102. Typically, the outer layers serves as an outer casing for thepet chew surrounding the inner member, together forming a stick shapeproduct.

Cross section outline shape of the Artificial Bully Stick pet chew ofpresent invention resembles the cross section outline shape of naturalBully Sticks, with a purpose to imitate Bully Sticks. Natural bullysticks have various cross section outline shapes which are inherentlydetermined by raw material of pizzles. Preferably, cross section of theArtificial Bully Stick pet chew of present invention is substantiallywith an outline shape similar to letter “B”, or peanut, or arabicnumerals “8”, imitating a typical cross section outline shape oftraditional bully sticks as aforementioned. Now refer to FIG. 1, 0100 isan extruded pet chew with a typical cross section outline shape similarto letter “B”, with a purpose to imitate a typical cross section outlineshape of traditional bully sticks.

Some other alternative outline shapes for the Artificial Bully Stick (orBully-Stick-LIKE) pet chew can refer to the various ones thattraditional bully stick may feature with as described in FIGS. 11 and12.

Preferably, Artificial Bully Stick pet chew (or pet chew member) ofpresent invention has a groove longitudinally along the whole pet chewstick body, with a purpose to imitate a typical inherent groove oftraditional Bully Stick products. Now refer to FIG. 1, 0100 is anextruded pet chew with 0202, the groove along the stick body to imitatenatural Bully Sticks, which is formed by extruder die with pre-designshape forming a groove in extruding process.

It should be noted that, all prior arts are silent to create a pet chewwith features of the following AS A WHOLE: it's an artificial bullystick, it's an extruded stick formed from a composition material withpizzle ingredient and plant ingredient, with a hard outer layers and ainner member, with cross section outline shape of “B”, or peanut, or “8”and with a groove longitudinally along its stick body.

Preferably, outer layer of the Artificial Bully Stick (orBully-Stick-LIKE) pet chew stick of present invention issemi-transparent. And preferably, the outer layer presents fiber-liketexture. These are in a purpose to imitate a typical outer layer textureof traditional Bully Sticks. The thickness of outer layer of theArtificial Bully Stick of present invention is typically 1 mm-5 mm,imitating the thickness feature of traditional bully stick products.

Preferably, inner member of the Artificial Bully Stick pet chew ofpresent invention is comparatively more unconsolidated or looser intexture than the muscle outer layer. Preferably, inner member of theArtificial Bully Stick pet chew of present invention has some smallholes spread substantially homogeneously to the inner member body. Nowrefer to FIG. 1, 0100 is an extruded pet chew with inner member 0102comparatively looser than muscle out layer 0101. Preferably, there aresome tiny holes spread substantially homogeneously to the inner memberbody.

Preferably, inner member color of the Artificial Bully Stick (orBully-Stick-LIKE) pet chew is lighter than outer layer color. Now referto FIG. 1, 0100 is an extruded pet chew with inner member of 0102 islighter than muscle outer layer 0101 in color. Inner member color istypically white or yellowing white. Outer layer color is typically lightbrown, brown, dark brown, red brown or muscle color.

Preferably, the Artificial Bully Stick (or Bully-Stick-LIKE) pet chewincludes artificial pizzle flavor (or say bully stick flavor) in itsformula, which further enhances its attraction to consumers.

In some embodiments of present invention, the outer layer hardness ofthe Artificial Bully Stick pet chew is with a durometer value between 80and 100. In other embodiments of present invention, the outer layerhardness of the edible pet chew is with a durometer value between 60 and80. In other embodiments of present invention, the outer layer hardnessof the edible pet chew is with a durometer value between 50 and 60. Inother embodiments of present invention, the outer layer hardness of theedible pet chew is with a durometer value between 40 and 50.

Now to disclose formulas that form the Artificial Bully Stick (orBully-Stick-LIKE) pet chew.

Now to define the phrase of “on an as formulated basis” in presentinvention that may be used in following paragraphs. It is about a meansto determine weight percentages of an ingredient in a product. “On an asformulated basis” is also a method that currently FDA (or AAFCO)organizations of USA usually utilize to determine weight percentage foran ingredient in a product. By the means of “on an as formulated basis”,the weight percentage of an ingredient in a food is determined as it isadded in the formulation of the food, including its inherent watercontent, not counting the water added for processing. All weightpercentage values of ingredients appearing in present invention applythis “on an as formulated basis” rule.

The formula of the Artificial Bully Stick (or Bully-Stick-LIKE) pet chewof present invention includes pizzle (or animal penis) ingredient on anas formulated basis. The advantages of including pizzle ingredient inthe formula go as follows (from point 1 to 4):

1. This product is an extruded Artificial Bully Stick pet chew withcomposition materials intended to imitate the properties of traditionalbully stick products. A formula with pizzle will make the pet chew notonly with a traditional bully stick appearance, but also with real bullystick ingredients, where product formula feature is in conformity withproduct appearance. Selling points of finished products are enhanced bythe conformity.

2. Another advantage of applying pizzle ingredient to the ArtificialBully Stick pet chew formula is that, it provides a perfect means tomake full use of pizzle leftovers created from genuine bully stickmanufacturing industry. A marketable genuine bully stick need be fairlylong, for example at least longer than 4″. A bully stick product lessthan for example 4″ has a jeopardy of dog choking. Most popular bullystick length welcome by consumers is 6″ and 12″. Producing 6″/12″ bullysticks by cutting a pizzle with initial length to desired lengthcertainly generate a lot of small sized pizzle segments. These segmentswere purchased with a full price but manufacturers didn't come up with amethod to make good use of them. The Artificial Bully Stick pet chew ofpresent invention can well make use of the pizzle segments by forexample grinding them to small piece and having them added to itscomposition formula.

3. Yet another advantage of applying pizzle ingredient to the ArtificialBully Stick pet chew formula is that, the pizzle ingredient can providenatural pizzle flavor to the pet chew without adding artificial flavors.Natural pizzle flavor is thought to be healthier element than artificialpizzle flavor.

4. Pizzle ingredient is a natural premium protein source for a pet chewproduct.

Preferably, the Artificial Bully Stick (or Bully-Stick-LIKE) pet chew ofpresent invention includes at least 3% pizzle (or animal penis)ingredient in formula. The reason why it has to be with “at least 3%”pizzle ingredients goes as follows (point 1 and 2):

1. “At least 3% pizzle” provides basic inherent attractant attractingdogs to chew on. Per palatability tests conducted by present inventor,this Artificial Bully Stick pet chew with less than 3% can't providebasic inherent attraction to dogs without aid of other attractantingredient. “At least 3% pizzle” offering “start point” palatability. Weconducted palatability contrast tests to determine the smallestpercentage of pizzle ingredient to put into the Artificial Bully Stickpet chew. The test interprets that when the pizzle percentage goes up to3% or larger than 3%, a jump of number of preference appears v.s. plainextruded stick chews w/o pizzle ingredient. And the preference isconsistent when the pizzle percentage stays at 3% to 10%. Therefore 3%is determined to be the minimum pizzle percentage in the ArtificialBully Stick pet chew.

2. At least 3% pizzle in formula enables product labeling to claim “withpizzle”, or “with real pizzle”, or “with bully stick ingredient” or“with real bully stick” on consumer packages, enhancing product sellingpoints to consumers. A product with less than 3% pizzle can't indicate“with pizzle” on package labels legally. This is a favorable advantagefor the Artificial Bully Stick pet chew product to indicate “withpizzle” as a part of product name which makes the product attractive toconsumers (remarks: if the ingredient goes to at least 25%, it will beapplied with “dinner” rule in labeling). According to labeling modelregulations by AAFCO (the Association of American Feed ControlOfficials), an ingredient can't appear as a part of product name or behighlighted on the principal display panel if the ingredient accountsfor less than 3% in product formula on an as formulated basis.

In some embodiments, the Artificial Bully Stick (or Bully-Stick-LIKE)pet chew (or pet chew member) includes 3%-50% pizzle ingredient.

In some embodiments, the Artificial Bully Stick (or Bully-Stick-LIKE)pet chew (or pet chew member) includes 5%-65% (more typically 10%-25%)pizzle ingredient on an as formula basis in its formula. TheBully-Stick-LIKE pet chew (or pet chew member) with over 50% (especiallyover 65%) pizzle ingredient is considered too expensive, which couldviolate the initial intention of introducing this product. Also TheArtificial Bully Stick pet chew (or pet chew member) with over 50%(especially over 65%) pizzle ingredient is considered to be able to ruinthe “durability” of the pet chew. The reason is, the more an extrudedpet chew contains meat (meat by-product), the less durability theextruded pet chew will be with. Pizzle is an animal sourcemeat-by-product-ingredient. According to R&D findings by the inventor,10%-25% pizzle ingredient in the Artificial Bully Stick pet chew (or petchew member) is an optimized one, which provides a balance betweendurability, material cost, sufficient inherent natural pizzle flavor andnatural protein source.

We conducted palatability contrast tests to determine the startingpercentage of pizzle ingredient to put into the Artificial Bully Stickpet chew that can secure an absolute preference for dogs for the petchew. The test interprets that when the pizzle percentage goes up to 10%or larger than 10%, an absolute preference appears v.s. plain extrudedstick chews w/o pizzle ingredient. On the other hand, the more pizzle ina pet chew, the more expensive the pet chew will be. 10%-25% is apreferred pizzle percentage range in the Artificial Bully Stick pet chewthat can provide a balance between “palatability” and cost.

Preferably, the Artificial Bully Stick (or Bully-Stick-LIKE) pet chew ofpresent invention includes a plant ingredient in the formula. ThisArtificial Bully Stick pet chew product is an extruded product. Plantingredient is an often-used material for extruded products withadvantages of (point 1, 2 and 3):

1. Significantly lower cost than animal ingredients.

2. Provides vegetable nutrition offering a nutrition balance and ahealthy diet.

3. Facilitates to make the Artificial Bully Stick pet chew with idealdurability/hardness which enables it to imitate this essential propertyof traditional bully sticks. Plants especially plant starch is a goodmaterial for extruded products which can facilitate the achievement ofideal durability/hardness especially in an extruding process. A theoryexplains how it works: When the starch part of plant material is cookedor heated at a particular temperature in extruder (the temperature isgenerally >40° C. and what the particular temperature depends on thenature of various types of the starch), heat causes the crystallineregions of the starch to become diffuse, so that the chains begin toseparate into an amorphous form. The intermolecular bonds of starchmolecules begin to break down. Starch dissolves in water to a sort ofpaste status. Thus gelatinization occurs in the starch which offers thedurability/hardness property for the pet chew.

A typical material working as a plant ingredient is plant starch, suchas (but not limited to) corn starch, sweet potato starch, tapioca starchand potato starch.

In some embodiments, the pet chew product includes 20%-95% (typically20%-50%) plant ingredient in weight on an as formulated basis.

It should be noted that the “plant” ingredient in present inventionrefers to all edible plant materials and edible-plant-derived materials,such as (but not limited to) vegetables, fruit, edible-plant-derivedmaterials, vegetable-derived materials, fruit-derived materials, plantprotein, vegetable protein, plant starch, vegetable starch, grains,cereals, corn, gluten-free edible plant and gluten-free vegetables.Gluten-free plant and gluten-free vegetables are preferred materials toform the “plant ingredient” since gluten materials are considered byexperts in this industry as the ones that could potentially make dogsallergic. Examples of gluten-free plant material are tapioca, soybean,sweet potato, potato and carrot.

The reasons why it is preferred to be with “<50% plant ingredients” goesas follows:

Since dogs are carnivorous, plant material does not attract pets verymuch. A pet chew product with too high plant percentage (over 50%)existing in the formula is less attractive to dogs, since dogs do notprefer vegetal material. Our tests indicate that, in an extruded petchew product, <50% plant ingredient by weight can achieve a goodmalleability and durability for an extruded piece. Too much plantingredients in it will reduce the palatability or attraction of the petchew significantly. Our tests indicate that, in a pet chew product, whenplant ingredient being >50% by weight, plant ingredient will be anabsolutely primary ingredient, which makes the pet chew NOT good inpalatability performance and not attractive to dogs. Therefore, in a petchew product, “>50% plant ingredient isn't a preferred option to formthe extruded pet chew of the present invention.

Preferably, the Artificial Bully Stick (or Bully-Stick-LIKE) pet chewstick is typically with a length of about 6″ or 12″, which is consideredas most popular stick length welcome by consumers. Diameter of the chewstick could be 1 cm to 5 cm.

Preferably, the Artificial Bully Stick (or Bully-Stick-LIKE) pet chewmember includes a meat (meat by-product) ingredient in the formula.

It should be noted that the “meat” ingredient in present invention isdefined as the material selected from (but not limited to) the groupconsisting of: animal flesh, animal muscle, poultry meat, chicken,chicken breast, duck, goose, turkey, venison, porcine meat, pork, bovinemeat, beef, mutton, lamb, goat meat, fish, meat meal, chicken meal, fishmeal, meat derived ingredient and poultry derived ingredient.

It should also be noted that the “meat by-product” ingredient in presentinvention is defined as the material typically selected from (but notlimited to) the group consisting of: porcine meat by-product, poultryby-product, bovine meat by-product, animal viscera, animal stomach,animal tongue, animal kidney, animal blood, animal bone, partiallydefatted low temperature fatty tissue, animal intestines, animal spleen,animal liver, animal lung, animal heart, animal pizzle, meat by-productmeal, poultry by-product meal, meat by-product derived ingredient,poultry by-product derived ingredient, animal fat and animal oil. Itshould be noted that the “meat by-product” in present invention doesn'tinclude animal hide/skin material and collagen material with the reasonsof: A, both animal hide/skin material and collagen don't have attractiveflavor urging dogs to chew. B, manufacture of animal hide and collagenis relatively unregulated industry. It may create pollution toenvironment. H2O2 and NaOH chemicals that are used for rawhidemanufacture and heavy metals may remain in finished products which harmsdogs' health.

Meat (meat by-product) ingredient is an often-used material for extrudedproducts with advantages of (point 1 and 2):

1. Inherent good palatability. Dogs are carnivorous, which have aninherent appetite to eat meat (meat by-product) food. Meat (meatby-product) ingredients in a pet chew works as an attractant providinginherent good palatability for the pet chew.

2. Nutrition. Meat (meat by-product) as a perfect source of animalprotein, offering a good nutrition to dogs.

In some embodiments, the Artificial Bully Stick (or Bully-Stick-LIKE)pet chew (or pet chew member) includes 3%-80% (typically 10%-50%) meatingredients in its formula on an as formula basis.

The reason why it has to be with “at least 3% meat (meat by-product)ingredients” goes as follows (point 1 and 2):

1. “At least 3% meat (meat by-product)” provides basic inherentattractant attracting dogs to chew on. Per palatability tests conductedby present inventor, this Artificial Bully Stick pet chew with less than3% can't provide basic inherent attraction to dogs without aid of otherattractant ingredient. “At least 3% meat (meat by-product)” offering“start point” palatability.

2. At least 3% meat (meat by-product) in formula enables productlabeling to claim “with meat (meat by-product)” or “with real meat (meatby-product)” on consumer packages, enhancing product selling points toconsumers. A product with less than 3% meat (meat by-product) can'tindicate “with meat (meat by-product)” on package labels legally. Thisis a favorable advantage for the Artificial Bully Stick pet chew productto indicate “with meat (meat by-product)” as a part of product namewhich makes the product attractive to consumers (remarks: if theingredient goes to at least 25%, it will be applied with “dinner” rulein labelling). According to labeling model regulations by AAFCO (theAssociation of American Feed Control Officials), an ingredient can'tappear as a part of product name or be highlighted on the principaldisplay panel if the ingredient accounts for less than 3% in productformula on an as formulated basis.
